摘 要:利用主矿体首采区已施工的50m×50m网度的钻探工程,通过稀空法进行论证,分别通过150m×150m网度稀空至300m×300m网度和50m×50m网度稀空至150m×150m网度,对铝土矿矿体形态、品位及矿石量变化进行对比分析,结合矿区勘查类型主要参数及变化,以论证矿区勘查工程间距的合理性。为矿区勘查工程间距的确定提供依据,以满足矿区勘查工作的要求。Using the drilling project with a mesh size of 50m×50m that has already been constructed in the first mining area of the main ore body,this paper conducts a comparative analysis of the morphology,grade,and ore volume changes of the bauxite ore body through the sparse space method.The spacing between exploration projects in the mining area is demonstrated by comparing the sparse space of 150m×150m mesh to 300m×300m mesh and the sparse space of 50m×50m mesh to 150m×150m mesh.Combined with the main parameters and changes of exploration types in the mining area,the rationality of the spacing between exploration projects in the mining area is demonstrated.Provide a basis for determining the spacing of mining area exploration projects to meet the requirements of mining area exploration work.
